Parque Natural Municipal Chico Mendes, Urban park and nature reserve in Recreio dos Bandeirantes, Rio de Janeiro, Brazil.

Parque Natural Municipal Chico Mendes covers 43 hectares around the Lagoinha das Tachas in Recreio dos Bandeirantes. It protects one of the last near-intact stretches of restinga and wetland in Rio de Janeiro, with bromeliads, ingá and pitangueira trees. The park has exhibition rooms, a library, an auditorium, walking trails, picnic areas and a wooden playground.

The reserve originated with municipal law 948 of 22 November 1959, which made the Lagoinha das Tachas area non aedificandi forest reserve; later decrees shrank it. On 6 May 1989 Mayor Marcello Alencar signed the decree creating the 43.6-hectare park, named after rubber tapper leader Chico Mendes, murdered in Xapuri in December 1988; his widow attended.

The park is named after Chico Mendes, the Amazon rubber tapper leader murdered in Xapuri, Acre, in December 1988. Its creation followed a campaign led in 1989 by Ribeiro José Francisco, president of the Recreio dos Bandeirantes residents' association (AMOR), who mobilised politicians, artists and ecologists; Chico Mendes's widow attended the public act of 6 May 1989. Today the RioZoo Foundation runs environmental education projects with universities such as UFRJ, UFRRJ, UERJ and UNESA.

The park covers 43 hectares and has walking trails, benches, picnic areas, a playground with wooden toys, an auditorium, a library and parking. Visits are free, and staff lead supervised tours of nurseries holding threatened species such as the broad-snouted caiman, land tortoises and the three-toed sloth.

The park's 43 hectares were once the Parque da Lagoinha, listed by the Guanabara state heritage authority in 1965. In May 1989 mayor Marcello Alencar signed the decree creating the reserve in the presence of Chico Mendes's widow. The Fundação RIOZOO runs research with UFRJ, UFRRJ, UERJ and UNESA.
